BOILER COMPOUND.

No Drawing. Application filed February 12, 1924, Serial No; 692,435.

To all whom it may homem: twenty pounds to every eight thousand gal- Be it known that I, CHARLES E. Guns, lons of water as this will break up all forcitizen of the United States, residing at eign matter in the water. For water that Casper, in the county of Natrona and State has carbonate lime or any soft scale forming of Wyoming, have invented certain new matter in it, it is preferable to use one halt and useful Improvements in Boiler Comof the amount used to break up alkali wapounds, of which the following is a specifiter. In speaking of the compound in the cation. examples it should be borne in mind that 55 The present invention relates to a boiler I mean the mixture of the dry ingredients compound and has for its principal object namely four pounds of calcium oxide (unto provide a. mixture to be used in boilers slacked rock lime), five pounds of soda ash for dissolving the scale which forms thereand one pound of oxalic acid mixed with in without in any way injuring the boiler. eight gallons of boiling water; after other 60 The compound consists of a mixture oi ingredients are thoroughly mixed, I add soda ash, rock lime, oxalic acid and crude two gallons of crude (unrefined) oil. The oil. In forming the composition I take five oil mentioned above is that which has been pounds of the soda ash, four pounds of the taken from the ground and having not underrock lime, and one pound of the oxalic acid gone treatment whatsoever. The. reason I and after grinding them thoroughly mix use calcium oxide (unslacked rock lime) is 20 them with two gallons of crude oil. that when it is mixed with the other ingre- The proportion of the ingredients outclients, and is pumped or injected into a lined above gives the best results and will. boiler, it does not settle to the bottom, as dissolve the scale within a few hours.
